How would you add the custom field to the core.php, I have tried {$user.customFields.field_id} but it doesn't work. I want to add a custom field to the Helper, for the user blurb "Title, gender, age, from location, custom field".

To be, or not to be: that is the core.php.
What's in a custom field? That which we call a rose, by any other custom field would smell as sweet.
Now is the Helper of our discontent, made glorious summer by this sun of York.
